Hurricane Irma: Facts, FAQs, and how to help

Hurricane Irma hit Florida as a Category 4 storm the morning of Sept. 10, 2018, ripping off roofs, flooding coastal cities, and knocking out power to more than 6.8 million people. By Sept. 11, Irma weakened significantly to a tropical storm as it powered north toward Georgia and Alabama. At 11 p.m. later that day, it weakened further to a tropical depression, and by Sept. 13, it had dissipated over western Tennessee.

The storm and its aftermath has killed at least 38 in the Caribbean, 34 in Florida, three in Georgia, four in South Carolina, and one in North CarolinaIrma is the fifth-costliest hurricane to hit the mainland United States, causing an estimated $50 billion in damage, according to the National Hurricane Center.

FAQs: What you need to know about Hurricane Irma, and learn how you can help

 

How did Hurricane Irma develop?

Hurricane Irma began Aug. 30 near the Cape Verde Islands. It was the ninth named storm and fourth hurricane of the 2017 storm season.

Irma developed from a tropical wave that developed off the West African coast two days earlier. It rapidly strengthened into a Category 2 storm within 24 hours. Irma’s intensity fluctuated in the days to follow and on Sept. 4 became a Category 4 hurricane.

A day later on Sept. 5, it grew to Category 5 strength. Irma wrought catastrophe in Barbuda and parts of the U.S. and British Virgin Islands. Puerto Rico, the Dominican Republic, and Haiti each experienced flooding and heavy damage in some areas, but the storm left much less destruction than expected.

Hurricane Irma downgraded to a Category 4 Sept. 8, but maintained winds around 150 mph. The threshold for a Category 5 is 157 mph. Irma made landfall over mainland Florida early Sept. 10 as a Category 4 hurricane. From there, it weakened significantly to a tropical storm Sept. 11 as it powered north toward Georgia and Alabama. At 11 p.m. later that day, it weakened further to a tropical depression, and by Sept. 13, it had dissipated over western Tennessee.

Hurricane Jose was on Irma’s tail, but weakened to a Category 1 storm before stalling out at sea.

Why is Hurricane Irma a big deal?

Irma is the fifth-costliest hurricane to hit the mainland United States and caused an estimated $50 billion in damage, according to the National Hurricane Center. At one point, Hurricane Irma was the strongest hurricane the National Hurricane Center has ever recorded in the Atlantic outside of the Caribbean Sea and Gulf of Mexico. It was moving as a Category 5 storm, which means it had sustained wind speeds greater than 157 mph. Category 5 storms cause catastrophic damage when they make landfall. Irma hit the Florida Keys as a Category 4 hurricane and then the mainland as a Category 3.

Hurricane Matthew hit the southern part of Haiti as a Category 4 storm Oct. 4, 2016, and the country still hasn’t fully recovered from that devastating system. Projections had it hitting Haiti hard, but the country was spared from severe devastation.

How has World Vision responded?

In the immediate aftermath, World Vision sent semitrucks full of relief supplies to several church partners in Immokalee, Fort Myers, and the Florida Keys. We were able reach more than 18,000 people in some of the hardest-hit areas with food, water, hygiene supplies, and other items. About 400 affected families also received $500 gift cards so they could purchase items they needed most, including materials to repair their homes.

 

Thanks to generous donors and corporate partners, we were able to keep our warehouses around the country well-stocked to quickly respond to hurricane Irma, Harvey, and Maria simultaneously. Our team was also able to deliver generators to local partners, including churches that needed power to serve hot meals to storm survivors. While the relief phase has moved toward rebuilding, we have committed to providing regular supplies shipments to a church partner in Immokalee to ensure their community is supported through the difficult recovery.

World Vision staff in Haiti and the Dominican Republic also responded to damage in their countries, although they avoided the more severe affects felt in other parts of the Caribbean.
